This application isa continuation of U.S. patent application Ser. No. 17/559,229, filed on Dec. 22, 2021, which claims the benefit of priority to U.S. Provisional Patent Application Ser. No. 63/197,608, filed Jun. 7, 2021, and entitled “MEC V2X API INTEROPERABILITY SUPPORT FOR MULTIPLE V2X MESSAGE BROKERS,” each of which patent application is incorporated herein by reference in its entirety.

Aspects pertain to wireless communications including edge computing and next generation (NG) communications. Some aspects relate to Multi-Access Edge Computing (MEC) vehicle-to-everything (V2X) application programming interface (API) interoperability support for multiple V2X message brokers.

Edge computing, at a general level, refers to the transition of compute and storage resources closer to endpoint devices (e.g., consumer computing devices, user equipment, etc.) to optimize total cost of ownership, reduce application latency, improve service capabilities, and improve compliance with security or data privacy requirements. Edge computing may, in some scenarios, provide a cloud-like distributed service that offers orchestration and management for applications among many types of storage and compute resources. As a result, some implementations of edge computing have been referred to as the “edge cloud” or the “fog”, as powerful computing resources previously available only in large remote data centers are moved closer to endpoints and made available for use by consumers at the “edge” of the network.

Edge computing use cases in mobile network settings have been developed for integration with MEC approaches, also known as “multi-access edge computing.” MEC approaches are designed to allow application developers and content providers to access computing capabilities and an information technology (IT) service environment in dynamic mobile network settings at the edge of the network. Limited standards have been developed by the European Telecommunications Standards Institute (ETSI) industry specification group (ISG) in an attempt to define common interfaces for the operation of MEC systems, platforms, hosts, services, and applications.

Edge computing, MEC, and related technologies attempt to provide reduced latency, increased responsiveness, and more available computing power than offered in traditional cloud network services and wide area network connections. However, the integration of mobility and dynamically launched services to some mobile use and device processing use cases has led to limitations and concerns with orchestration, functional coordination, and resource management, especially in complex mobility settings where many participants (devices, hosts, tenants, service providers, operators) are involved.

Similarly, Internet of Things (IoT) networks and devices are designed to offer a distributed compute arrangement, from a variety of endpoints. IoT devices are physical or virtualized objects that may communicate on a network and may include sensors, actuators, and other input/output components, which may be used to collect data or perform actions in a real-world environment. For example, IoT devices may include low-powered endpoint devices that are embedded or attached to everyday things, such as buildings, vehicles, packages, etc., to provide an additional level of artificial sensory perception of those things. Recently, IoT devices have become more popular and thus applications using these devices have proliferated.

The deployment of various Edge, Fog, MEC, private enterprise networks (e.g., software-defined wide-area networks, or SD-WANs), and IoT networks, devices, and services have introduced several advanced use cases and scenarios occurring at and towards the edge of the network. However, these advanced use cases have also introduced some corresponding technical challenges relating to security, processing, and network resources, service availability, and efficiency, among many other issues. One such challenge is MEC V2X API interoperability support for multiple V2X message brokers in a MEC infrastructure.

The following embodiments generally relate to methods, configurations, and apparatuses for providing MEC V2X API interoperability support for multiple V2X message brokers in a MEC infrastructure. The following examples introduce specific configurations and usage of the V2X information service (VIS) mesh control plane for providing MEC V2X API interoperability support. Example embodiments can be implemented in systems similar to those shown in any of the systems described below in reference to. Additional description of various network entities using, configuring, or performing the VIS functions is provided herein below in connection with at least-.

is a block diagramshowing an overview of a configuration for edge computing, which includes a layer of processing referred to in many of the following examples as an “edge cloud”. As shown, the edge cloudis co-located at an edge location, such as an access point or base station, a local processing hub, or a central office, and thus may include multiple entities, devices, and equipment instances. The edge cloudis located much closer to the endpoint (consumer and producer) data sources(e.g., autonomous vehicles, user equipment, business and industrial equipment, video capture devices, drones, smart cities and building devices, sensors and IoT devices, etc.) than the cloud data center. Compute, memory, and storage resources which are offered at the edges in the edge cloudare critical to providing ultra-low latency response times for services and functions used by the endpoint data sourcesas well as reduce network backhaul traffic from the edge cloudtoward cloud data centerthus improving energy consumption and overall network usages among other benefits.

Compute, memory, and storage are scarce resources, and generally decrease depending on the edge location (e.g., fewer processing resources being available at consumer endpoint devices, than at a base station, than at a central office). However, the closer that the edge location is to the endpoint (e.g., user equipment (UE)), the more that space and power are often constrained. Thus, edge computing attempts to reduce the number of resources needed for network services, through the distribution of more resources that are located closer to both geographically and in-network access time. In this manner, edge computing attempts to bring the compute resources to the workload data where appropriate or bring the workload data to the compute resources.

The following describes aspects of an edge cloud architecture that covers multiple potential deployments and addresses restrictions that some network operators or service providers may have in their infrastructures. These include a variety of configurations based on the edge location (because edges at a base station level, for instance, may have more constrained performance and capabilities in a multi-tenant scenario); configurations based on the type of compute, memory, storage, fabric, acceleration, or like resources available to edge locations, tiers of locations, or groups of locations; the service, security, and management and orchestration capabilities; and related objectives to achieve usability and performance of end services. These deployments may accomplish processing in network layers that may be considered as “near edge”, “close edge”, “local edge”, “middle edge”, or “far edge” layers, depending on latency, distance, and timing characteristics.

Edge computing is a developing paradigm where computing is performed at or closer to the “edge” of a network, typically through the use of a compute platform (e.g., x86 or ARM compute hardware architecture) implemented at base stations, gateways, network routers, or other devices which are much closer to endpoint devices producing and consuming the data. For example, edge gateway servers may be equipped with pools of memory and storage resources to perform computation in real-time for low latency use cases (e.g., autonomous driving or video surveillance) for connected client devices. As an example, base stations may be augmented with compute and acceleration resources to directly process service workloads for the connected user equipment, without further communicating data via backhaul networks. A s another example, central office network management hardware may be replaced with standardized compute hardware that performs virtualized network functions and offers compute resources for the execution of services and consumer functions for connected devices. Within edge computing networks, there may be scenarios in services in which the compute resource will be “moved” to the data, as well as scenarios in which the data will be “moved” to the compute resource. As an example, base station compute, acceleration and network resources can provide services to scale to workload demands on an as-needed basis by activating dormant capacity (subscription, capacity-on-demand) to manage corner cases, emergencies or to provide longevity for deployed resources over a significantly longer implemented lifecycle.

In some aspects, the edge cloudand the cloud data centercan be configured with V2X information service (VIS) functions. Example VIS functions include configuration of a V2X message subscription service for V2X message brokers, facilitating subscription of V2X message consumers to V2X message brokers, protocol conversion for subscription data communicated between V2X message consumers, and V2X message brokers, which functionalities are discussed in greater detail in connection with-.

illustrates operational layers among endpoints, an edge cloud, and cloud computing environments. Specifically,depicts examples of computational use cases, utilizing the edge cloudamong multiple illustrative layers of network computing. The layers begin at an endpoint (devices and things) layer, which accesses the edge cloudto conduct data creation, analysis, and data consumption activities. The edge cloudmay span multiple network layers, such as an edge devices layerhaving gateways, on-premise servers, or network equipment (nodes) located in physically proximate edge systems; a network access layer, encompassing base stations, radio processing units, network hubs, regional data centers (DC), or local network equipment (equipment); and any equipment, devices, or nodes located therebetween (in layer, not illustrated in detail). The network communications within the edge cloudand among the various layers may occur via any number of wired or wireless mediums, including via connectivity architectures and technologies not depicted. Any of the communication use casescan be configured with VIS functions, which may be performed by a communication node configured as an orchestration management entity or a MEC host within a MEC network, or (2) performed by a board management controller (BMC) of a computing node. Example VIS functions are discussed in greater detail in connection with-.

Examples of latency, resulting from network communication distance and processing time constraints, may range from less than a millisecond (ms) when among the endpoint layer, under 5 ms at the edge devices layer, to even between 10 to 40 ms when communicating with nodes at the network access layer. Beyond the edge cloudare core network layerand cloud data center layer, each with increasing latency (e.g., between 50-60 ms at the core network layer, to 100 or more ms at the cloud data center layer). As a result, operations at a core network data centeror a cloud data center, with latencies of at least 50 to 100 ms or more, will not be able to accomplish many time-critical functions of the use cases. Each of these latency values are provided for purposes of illustration and contrast; it will be understood that the use of other access network mediums and technologies may further reduce the latencies. In some examples, respective portions of the network may be categorized as “close edge”, “local edge”, “near edge”, “middle edge”, or “far edge” layers, relative to a network source and destination. For instance, from the perspective of the core network data centeror a cloud data center, a central office or content data network may be considered as being located within a “near edge” layer (“near” to the cloud, having high latency values when communicating with the devices and endpoints of the use cases), whereas an access point, base station, on-premise server, or network gateway may be considered as located within a “far edge” layer (“far” from the cloud, having low latency values when communicating with the devices and endpoints of the use cases). It will be understood that other categorizations of a particular network layer as constituting a “close”, “local”, “near”, “middle”, or “far” edge may be based on latency, distance, a number of network hops, or other measurable characteristics, as measured from a source in any of the network layers-.

The various use casesmay access resources under usage pressure from incoming streams, due to multiple services utilizing the edge cloud. To achieve results with low latency, the services executed within the edge cloudbalance varying requirements in terms of (a) Priority (throughput or latency; also referred to as service level objective or SLO) and Quality of Service (QoS) (e.g., traffic for an autonomous car may have higher priority than a temperature sensor in terms of response time requirement; or, a performance sensitivity/bottleneck may exist at a compute/accelerator, memory, storage, or network resource, depending on the application); (b) Reliability and Resiliency (e.g., some input streams need to be acted upon and the traffic routed with mission-critical reliability, whereas some other input streams may tolerate an occasional failure, depending on the application); and (c) Physical constraints (e.g., power, cooling, and form-factor).

The end-to-end service view for these use cases involves the concept of a service flow and is associated with a transaction. The transaction details the overall service requirement for the entity consuming the service, as well as the associated services for the resources, workloads, workflows, and business functional and business level requirements. The services executed with the “terms” described may be managed at each layer in a way to assure real-time, and runtime contractual compliance for the transaction during the lifecycle of the service. When a component in the transaction is missing its agreed to Service Level Agreements (SLA), the system as a whole (components in the transaction) may provide the ability to (1) understand the impact of the SLA violation, and (2) augment other components in the system to resume overall transaction SLA, and (3) implement steps to remediate.

Thus, with these variations and service features in mind, edge computing within the edge cloudmay provide the ability to serve and respond to multiple applications of the use cases(e.g., object tracking, video surveillance, connected cars, etc.) in real-time or near real-time, and meet ultra-low latency requirements for these multiple applications. These advantages enable a whole new class of applications (Virtual Network Functions (VNFs), Function as a Service (FaaS), Edge as a Service (EaaS), standard processes, etc.), which cannot leverage conventional cloud computing due to latency or other limitations.

However, with the advantages of edge computing come the following caveats. The devices located at the edge are often resource-constrained and therefore there is pressure on the usage of edge resources. Typically, this is addressed through the pooling of memory and storage resources for use by multiple users (tenants) and devices. The edge may be power and cooling constrained and therefore the power usage needs to be accounted for by the applications that are consuming the most power. There may be inherent power-performance tradeoffs in these pooled memory resources, as many of them are likely to use emerging memory technologies, where more power requires greater memory bandwidth. Likewise, improved security of hardware and root of trust trusted functions are also required because edge locations may be unmanned and may even need permission access (e.g., when housed in a third-party location). Such issues are magnified in the edge cloudin a multi-tenant, multi-owner, or multi-access setting, where services and applications are requested by many users, especially as network usage dynamically fluctuates and the composition of the multiple stakeholders, use cases, and services changes.

At a more generic level, an edge computing system may be described to encompass any number of deployments at the previously discussed layers operating in the edge cloud(network layers-), which provide coordination from the client and distributed computing devices. One or more edge gateway nodes, one or more edge aggregation nodes, and one or more core data centers may be distributed across layers of the network to provide an implementation of the edge computing system by or on behalf of a telecommunication service provider (“telco”, or “TSP”), internet-of-things service provider, the cloud service provider (CSP), enterprise entity, or any other number of entities. Various implementations and configurations of the edge computing system may be provided dynamically, such as when orchestrated to meet service objectives.

Consistent with the examples provided herein, a client compute node may be embodied as any type of endpoint component, device, appliance, or another thing capable of communicating as a producer or consumer of data. Further, the label “node” or “device” as used in the edge computing system does not necessarily mean that such node or device operates in a client or agent/minion/follower role; rather, any of the nodes or devices in the edge computing system refer to individual entities, nodes, or subsystems which include discrete or connected hardware or software configurations to facilitate or use the edge cloud.

As such, the edge cloudis formed from network components and functional features operated by and within edge gateway nodes, edge aggregation nodes, or other edge compute nodes among network layers-. The edge cloudthus may be embodied as any type of network that provides edge computing and/or storage resources that are proximately located to radio access network (RAN) capable endpoint devices (e.g., mobile computing devices, IoT devices, smart devices, etc.), which are discussed herein. In other words, the edge cloudmay be envisioned as an “edge” that connects the endpoint devices and traditional network access points that serve as an ingress point into service provider core networks, including mobile carrier networks (e.g., Global System for Mobile Communications (GSM) networks, Long-Term Evolution (LTE) networks, 5G/6G networks, etc.), while also providing storage and/or compute capabilities. Other types and forms of network access (e.g., Wi-Fi, long-range wireless, wired networks including optical networks) may also be utilized in place of or in combination with such 3GPP carrier networks.

The network components of the edge cloudmay be servers, multi-tenant servers, appliance computing devices, and/or any other type of computing device. For example, the edge cloudmay include an appliance computing device that is a self-contained electronic device including a housing, a chassis, a case, or a shell. In some circumstances, the housing may be dimensioned for portability such that it can be carried by a human and/or shipped. Example housings may include materials that form one or more exterior surfaces that partially or fully protect the contents of the appliance, in which protection may include weather protection, hazardous environment protection (e.g., EMI, vibration, extreme temperatures), and/or enable submergibility. Example housings may include power circuitry to provide power for stationary and/or portable implementations, such as AC power inputs, DC power inputs, AC/DC or DC/AC converter(s), power regulators, transformers, charging circuitry, batteries, wired inputs and/or wireless power inputs. Example housings and/or surfaces thereof may include or connect to mounting hardware to enable attachment to structures such as buildings, telecommunication structures (e.g., poles, antenna structures, etc.), and/or racks (e.g., server racks, blade mounts, etc.). Example housings and/or surfaces thereof may support one or more sensors (e.g., temperature sensors, vibration sensors, light sensors, acoustic sensors, capacitive sensors, proximity sensors, etc.). One or more such sensors may be contained in, carried by, or otherwise embedded in the surface and/or mounted to the surface of the appliance. Example housings and/or surfaces thereof may support mechanical connectivity, such as propulsion hardware (e.g., wheels, propellers, etc.) and/or articulating hardware (e.g., robot arms, pivotable appendages, etc.). In some circumstances, the sensors may include any type of input devices such as user interface hardware (e.g., buttons, switches, dials, sliders, etc.). In some circumstances, example housings include output devices contained in, carried by, embedded therein, and/or attached thereto. Output devices may include displays, touchscreens, lights, LEDs, speakers, I/O ports (e.g., USB), etc. In some circumstances, edge devices are devices presented in the network for a specific purpose (e.g., a traffic light), but may have processing and/or other capacities that may be utilized for other purposes. Such edge devices may be independent of other networked devices and may be provided with a housing having a form factor suitable for its primary purpose; yet be available for other compute tasks that do not interfere with its primary task. Edge devices include Internet of Things devices. The appliance computing device may include hardware and software components to manage local issues such as device temperature, vibration, resource utilization, updates, power issues, physical and network security, etc. Example hardware for implementing an appliance computing device is described in conjunction with. The edge cloudmay also include one or more servers and/or one or more multi-tenant servers. Such a server may include an operating system and a virtual computing environment. A virtual computing environment may include a hypervisor managing (spawning, deploying, destroying, etc.) one or more virtual machines, one or more containers, etc. Such virtual computing environments provide an execution environment in which one or more applications and/or other software, code, or scripts may execute while being isolated from one or more other applications, software, code, or scripts.

In, various client endpoints(in the form of mobile devices, computers, autonomous vehicles, business computing equipment, industrial processing equipment) exchange requests and responses that are specific to the type of endpoint network aggregation. For instance, client endpointsmay obtain network access via a wired broadband network, by exchanging requests and responsesthrough an on-premise network system. Some client endpoints, such as mobile computing devices, may obtain network access via a wireless broadband network, by exchanging requests and responsesthrough an access point (e.g., cellular network tower). Some client endpoints, such as autonomous vehicles may obtain network access for requests and responsesvia a wireless vehicular network through a street-located network system. However, regardless of the type of network access, the TSP may deploy aggregation points,within the edge cloudto aggregate traffic and requests. Thus, within the edge cloud, the TSP may deploy various compute and storage resources, such as at edge aggregation nodes, to provide requested content. The edge aggregation nodesand other systems of the edge cloudare connected to a cloud or data center, which uses a backhaul networkto fulfill higher-latency requests from a cloud/data center for websites, applications, database servers, etc. Additional or consolidated instances of the edge aggregation nodesand the aggregation points,, including those deployed on a single server framework, may also be present within the edge cloudor other areas of the TSP infrastructure.

In an example embodiment, the edge cloudand the cloud or data centerutilize VIS functionsin connection with disclosed techniques. The VIS functionsmay be performed by a communication node configured as an orchestration management entity or a MEC host within a MEC network, or (2) performed by a board management controller (BMC) of a computing node. Example VIS functions are discussed in greater detail in connection with-.

illustrates deployment and orchestration for virtual edge configurations across an edge computing system operated among multiple edge nodes and multiple tenants. Specifically,depicts the coordination of a first edge nodeand a second edge nodein an edge computing system, to fulfill requests and responses for various client endpoints(e.g., smart cities/building systems, mobile devices, computing devices, business/logistics systems, industrial systems, etc.), which access various virtual edge instances. H ere, the virtual edge instances,(or virtual edges) provide edge compute capabilities and processing in an edge cloud, with access to a cloud/data centerfor higher-latency requests for websites, applications, database servers, etc. However, the edge cloud enables coordination of processing among multiple edge nodes for multiple tenants or entities.

In the example of, these virtual edge instances include: a first virtual edge instance, offered to a first tenant (Tenant), which offers the first combination of edge storage, computing, and services; and a second virtual edge, offering a second combination of edge storage, computing, and services. The virtual edge instances,are distributed among the edge nodes,, and may include scenarios in which a request and response are fulfilled from the same or different edge nodes. The configuration of the edge nodes,to operate in a distributed yet coordinated fashion occurs based on edge provisioning functions. The functionality of the edge nodes,to provide coordinated operation for applications and services, among multiple tenants, occurs based on orchestration functions.

In an example embodiment, the edge provisioning functionsand the orchestration functionscan utilize VIS functionsin connection with disclosed techniques. The VIS functionsmay be performed by a communication node configured as an orchestration management entity or a MEC host within a MEC network, or (2) performed by a board management controller (BMC) of a computing node. Example VIS functions are discussed in greater detail in connection with-.

It should be understood that some of the devices in the various client endpointsare multi-tenant devices where Tenantmay function within a tenant‘slice’ while Tenantmay function within a tenantslice (and, in further examples, additional or sub-tenants may exist; and each tenant may even be specifically entitled and transactionally tied to a specific set of features all the way day to specific hardware features). A trusted multi-tenant device may further contain a tenant-specific cryptographic key such that the combination of key and slice may be considered a “root of trust” (RoT) or tenant-specific RoT. An RoT may further be computed dynamically composed using a DICE (Device Identity Composition Engine) architecture such that a single DICE hardware building block may be used to construct layered trusted computing base contexts for layering of device capabilities (such as a Field Programmable Gate Array (FPGA)). The RoT may further be used for a trusted computing context to enable a “fan-out” that is useful for supporting multi-tenancy. Within a multi-tenant environment, the respective edge nodes,may operate as security feature enforcement points for local resources allocated to multiple tenants per node. Additionally, tenant runtime and application execution (e.g., in virtual edge instances,) may serve as an enforcement point for a security feature that creates a virtual edge abstraction of resources spanning potentially multiple physical hosting platforms. Finally, the orchestration functionsat an orchestration entity may operate as a security feature enforcement point for marshaling resources along tenant boundaries.

Edge computing nodes may partition resources (memory, central processing unit (CPU), graphics processing unit (GPU), interrupt controller, input/output (I/O) controller, memory controller, bus controller, etc.) where respective partitionings may contain an RoT capability and where fan-out and layering according to a DICE model may further be applied to Edge Nodes. Cloud computing nodes consisting of containers, FaaS engines, Servlets, servers, or other computation abstraction may be partitioned according to a DICE layering and fan-out structure to support an RoT context for each. Accordingly, the respective RoTs spanning devices in,, andmay coordinate the establishment of a distributed trusted computing base (DTCB) such that a tenant-specific virtual trusted secure channel linking all elements end to end can be established.

Further, it will be understood that a container may have data or workload-specific keys protecting its content from a previous edge node. As part of the migration of a container, a pod controller at a source edge node may obtain a migration key from a target edge node pod controller where the migration key is used to wrap the container-specific keys. When the container/pod is migrated to the target edge node, the unwrapping key is exposed to the pod controller that then decrypts the wrapped keys. The keys may now be used to perform operations on container-specific data. The migration functions may be gated by properly attested edge nodes and pod managers (as described above).

In further examples, an edge computing system is extended to provide for orchestration of multiple applications through the use of containers (a contained, deployable unit of software that provides code and needed dependencies) in a multi-owner, multi-tenant environment. A multi-tenant orchestrator may be used to perform key management, trust anchor management, and other security functions related to the provisioning and lifecycle of the trusted ‘slice’ concept in. For instance, an edge computing system may be configured to fulfill requests and responses for various client endpoints from multiple virtual edge instances (and, from a cloud or remote data center). The use of these virtual edge instances may support multiple tenants and multiple applications (e.g., augmented reality (AR)/virtual reality (V R), enterprise applications, content delivery, gaming, compute offload) simultaneously. Further, there may be multiple types of applications within the virtual edge instances (e.g., normal applications; latency-sensitive applications; latency-critical applications; user plane applications; networking applications; etc.). The virtual edge instances may also be spanned across systems of multiple owners at different geographic locations (or respective computing systems and resources which are co-owned or co-managed by multiple owners).

For instance, each edge node,may implement the use of containers, such as with the use of a container “pod”,providing a group of one or more containers. In a setting that uses one or more container pods, a pod controller or orchestrator is responsible for local control and orchestration of the containers in the pod. Various edge node resources (e.g., storage, compute, services, depicted with hexagons) provided for the respective edge slices of virtual edges,are partitioned according to the needs of each container.

With the use of container pods, a pod controller oversees the partitioning and allocation of containers and resources. The pod controller receives instructions from an orchestrator (e.g., performing orchestration functions) that instructs the controller on how best to partition physical resources and for what duration, such as by receiving key performance indicator (KPI) targets based on SLA contracts. The pod controller determines which container requires which resources and for how long to complete the workload and satisfy the SLA. The pod controller also manages container lifecycle operations such as: creating the container, provisioning it with resources and applications, coordinating intermediate results between multiple containers working on a distributed application together, dismantling containers when workload completes, and the like. Additionally, a pod controller may serve a security role that prevents the assignment of resources until the right tenant authenticates or prevents provisioning of data or a workload to a container until an attestation result is satisfied.

Also, with the use of container pods, tenant boundaries can still exist but in the context of each pod of containers. If each tenant-specific pod has a tenant-specific pod controller, there will be a shared pod controller that consolidates resource allocation requests to avoid typical resource starvation situations. Further controls may be provided to ensure the attestation and trustworthiness of the pod and pod controller. For instance, the orchestration functionsmay provision an attestation verification policy to local pod controllers that perform attestation verification. If an attestation satisfies a policy for a first tenant pod controller but not a second tenant pod controller, then the second pod could be migrated to a different edge node that does satisfy it. Alternatively, the first pod may be allowed to execute and a different shared pod controller is installed and invoked before the second pod executes.

illustrates additional compute arrangements deploying containers in an edge computing system. As a simplified example, system arrangements,depict settings in which a pod controller (e.g., container managers,, and container orchestrator) is adapted to launch containerized pods, functions, and functions-as-a-service instances through execution via compute nodes (e.g., compute nodesin arrangement) or to separately execute containerized virtualized network functions through execution via compute nodes (e.g., compute nodesin arrangement). This arrangement is adapted for use of multiple tenants in system arrangement(using compute nodes), where containerized pods (e.g., pods), functions (e.g., functions, VNFs,), and functions-as-a-service instances (e.g., FaaS instance) are launched within virtual machines (e.g., VMs,for tenants,) specific to respective tenants (aside from the execution of virtualized network functions). This arrangement is further adapted for use in system arrangement, which provides containers,, or execution of the various functions, applications, and functions on compute nodes, as coordinated by a container-based orchestration system.

The system arrangements depicted inprovide an architecture that treats VMs, Containers, and Functions equally in terms of application composition (and resulting applications are combinations of these three ingredients). Each ingredient may involve the use of one or more accelerator (FPGA, ASIC) components as a local backend. In this manner, applications can be split across multiple edge owners, coordinated by an orchestrator.

In the context of, the pod controller/container manager, container orchestrator, and individual nodes may provide a security enforcement point. However, tenant isolation may be orchestrated where the resources allocated to a tenant are distinct from resources allocated to a second tenant, but edge owners cooperate to ensure resource allocations are not shared across tenant boundaries. Or, resource allocations could be isolated across tenant boundaries, as tenants could allow “use” via a subscription or transaction/contract basis. In these contexts, virtualization, containerization, enclaves, and hardware partitioning schemes may be used by edge owners to enforce tenancy. Other isolation environments may include bare metal (dedicated) equipment, virtual machines, containers, virtual machines on containers, or combinations thereof.

In further examples, aspects of software-defined or controlled silicon hardware, and other configurable hardware, may integrate with the applications, functions, and services of an edge computing system. Software-defined silicon may be used to ensure the ability for some resource or hardware ingredient to fulfill a contractor service level agreement, based on the ingredient's ability to remediate a portion of itself or the workload (e.g., by an upgrade, reconfiguration, or provision of new features within the hardware configuration itself).

It should be appreciated that the edge computing systems and arrangements discussed herein may be applicable in various solutions, services, and/or use cases involving mobility. As an example,shows a simplified vehicle compute and communication use case involving mobile access to applications in an edge computing systemthat implements an edge cloud. In this use case, respective client compute nodes (or devices)may be embodied as in-vehicle compute systems (e.g., in-vehicle navigation and/or infotainment systems) located in corresponding vehicles that communicate with the edge gateway nodes (or devices)during traversal of a roadway. For instance, the edge gateway nodesmay be located in a roadside cabinet or other enclosure built into a structure having other, separate, mechanical utility, which may be placed along the roadway, at intersections of the roadway, or other locations near the roadway. As respective vehicles traverse along the roadway, the connection between its client compute nodeand a particular edge gateway nodemay propagate to maintain a consistent connection and context for the client compute node. Likewise, MEC nodes may aggregate at the high priority services or according to the throughput or latency resolution requirements for the underlying service(s) (e.g., in the case of drones). The respective edge gateway nodesinclude an amount of processing and storage capabilities and, as such, some processing and/or storage of data for the client compute nodesmay be performed on one or more of the edge gateway nodes.

The edge gateway nodesmay communicate with one or more edge resource nodes, which are illustratively embodied as compute servers, appliances, or components located at or in a communication base station(e.g., a base station of a cellular network). As discussed above, the respective edge resource nodesinclude an amount of processing and storage capabilities, and, as such, some processing and/or storage of data for the client compute nodesmay be performed on the edge resource node. For example, the processing of data that is less urgent or important may be performed by the edge resource node, while the processing of data that is of a higher urgency or importance may be performed by the edge gateway nodes(depending on, for example, the capabilities of each component, or information in the request indicating urgency or importance). Based on data access, data location, or latency, work may continue on edge resource nodes when the processing priorities change during the processing activity. Likewise, configurable systems or hardware resources themselves can be activated (e.g., through a local orchestrator) to provide additional resources to meet the new demand (e.g., adapt the compute resources to the workload data).

The edge resource node(s)also communicates with the core data center, which may include compute servers, appliances, and/or other components located in a central location (e.g., a central office of a cellular communication network). The core data centermay provide a gateway to the global network cloud(e.g., the Internet) for the edge cloudoperations formed by the edge resource node(s)and the edge gateway nodes. Additionally, in some examples, the core data centermay include an amount of processing and storage capabilities and, as such, some processing and/or storage of data for the client compute devices may be performed on the core data center(e.g., processing of low urgency or importance, or high complexity).

The edge gateway nodesor the edge resource nodesmay offer the use of stateful applicationsand a geographic distributed database. Although the stateful applicationsand databaseare illustrated as being horizontally distributed at a layer of the edge cloud, it will be understood that resources, services, or other components of the application may be vertically distributed throughout the edge cloud (including, part of the application executed at the client compute node, other parts at the edge gateway nodesor the edge resource nodes, etc.). Additionally, as stated previously, there can be peer relationships at any level to meet service objectives and obligations. Further, the data for a specific client or application can move from edge to edge based on changing conditions (e.g., based on acceleration resource availability, following the car movement, etc.). For instance, based on the “rate of decay” of access, a prediction can be made to identify the next owner to continue, or when the data or computational access will no longer be viable. These and other services may be utilized to complete the work that is needed to keep the transaction compliant and lossless.

In further scenarios, a container(or a pod of containers) may be flexibly migrated from an edge gateway nodeto other edge nodes (e.g.,,, etc.) such that the container with an application and workload does not need to be reconstituted, re-compiled, re-interpreted for migration to work. However, in such settings, there may be some remedial or “swizzling” translation operations applied. For example, the physical hardware at nodemay differ from edge gateway nodeand therefore, the hardware abstraction layer (HA L) that makes up the bottom edge of the container will be re-mapped to the physical layer of the target edge node. This may involve some form of late-binding technique, such as binary translation of the HA L from the container-native format to the physical hardware format, or may involve mapping interfaces and operations. A pod controller may be used to drive the interface mapping as part of the container lifecycle, which includes migration to/from different hardware environments.

The scenarios encompassed bymay utilize various types of MEC nodes, such as an edge node hosted in a vehicle (car/truck/tram/train) or other mobile units, as the edge node will move to other geographic locations along the platform hosting it. With vehicle-to-vehicle communications, individual vehicles may even act as network edge nodes for other cars, (e.g., to perform caching, reporting, data aggregation, etc.). Thus, it will be understood that the application components provided in various edge nodes may be distributed in static or mobile settings, including coordination between some functions or operations at individual endpoint devices or the edge gateway nodes, some others at the edge resource node, and others in the core data centeror global network cloud.

In an example embodiment, the edge cloudinutilizes VIS functionsin connection with disclosed techniques. The VIS functionsmay be performed by a communication node configured as an orchestration management entity or a MEC host within a MEC network, or (2) performed by a board management controller (BMC) of a computing node. Example VIS functions are discussed in greater detail in connection with-.

In further configurations, the edge computing system may implement FaaS computing capabilities through the use of respective executable applications and functions. In an example, a developer writes function code (e.g., “computer code” herein) representing one or more computer functions, and the function code is uploaded to a FaaS platform provided by, for example, an edge node or data center. A trigger such as, for example, a service use case or an edge processing event, initiates the execution of the function code with the FaaS platform.

In an example of FaaS, a container is used to provide an environment in which function code (e.g., an application that may be provided by a third party) is executed. The container may be any isolated execution entity such as a process, a Docker or Kubernetes container, a virtual machine, etc. Within the edge computing system, various datacenter, edge, and endpoint (including mobile) devices are used to “spin up” functions (e.g., activate and/or allocate function actions) that are scaled on demand. The function code gets executed on the physical infrastructure (e.g., edge computing node) device and underlying virtualized containers. Finally, the container is “spun down” (e.g., deactivated and/or deallocated) on the infrastructure in response to the execution being completed.

Further aspects of FaaS may enable deployment of edge functions in a service fashion, including support of respective functions that support edge computing as a service (Edge-as-a-Service or “EaaS”). Additional features of FaaS may include: a granular billing component that enables customers (e.g., computer code developers) to pay only when their code gets executed; common data storage to store data for reuse by one or more functions; orchestration and management among individual functions; function execution management, parallelism, and consolidation; management of container and function memory spaces; coordination of acceleration resources available for functions; and distribution of functions between containers (including “warm” containers, already deployed or operating, versus “cold” which require initialization, deployment, or configuration).

The edge computing systemcan include or be in communication with an edge provisioning node. The edge provisioning nodecan distribute software such as the example computer-readable (also referred to as machine-readable) instructionsof, to various receiving parties for implementing any of the methods described herein. The example edge provisioning nodemay be implemented by any computer server, home server, content delivery network, virtual server, software distribution system, central facility, storage device, storage disks, storage node, data facility, cloud service, etc., capable of storing and/or transmitting software instructions (e.g., code, scripts, executable binaries, containers, packages, compressed files, and/or derivatives thereof) to other computing devices. Component(s) of the example edge provisioning nodemay be located in a cloud, in a local area network, in an edge network, in a wide area network, on the Internet, and/or any other location communicatively coupled with the receiving party (or parties). The receiving parties may be customers, clients, associates, users, etc. of the entity owning and/or operating the edge provisioning node. For example, the entity that owns and/or operates the edge provisioning nodemay be a developer, a seller, and/or a licensor (or a customer and/or consumer thereof) of software instructions such as the example computer-readable instructions(also referred to as machine-readable instructions) of. The receiving parties may be consumers, service providers, users, retailers, OEMs, etc., who purchase and/or license the software instructions for use and/or re-sale and/or sub-licensing.
